Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 2,516,675, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 2,516,675 | |
| -1 | -2,516,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,516,675.
Example:
1 x 2,516,675 = 2,516,675
and
-1 x -2,516,675 = 2,516,675
Notice both answers equal 2,516,675
With that explanation out of the way, let's continue. Next, we take the number 2,516,675 and divide it by 2:
2,516,675 ÷ 2 = 1,258,337.5
If the quotient is a whole number, then 2 and 1,258,337.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 2,516,675 | |
| -1 | -2,516,675 |
Now, we try dividing 2,516,675 by 3:
2,516,675 ÷ 3 = 838,891.6667
If the quotient is a whole number, then 3 and 838,891.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 2,516,675 | |
| -1 | -2,516,675 |
Let's try dividing by 4:
2,516,675 ÷ 4 = 629,168.75
If the quotient is a whole number, then 4 and 629,168.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 2,516,675 | |
| -1 | 2,516,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 73 | 175 | 197 | 365 | 511 | 985 | 1,379 | 1,825 | 2,555 | 4,925 | 6,895 | 12,775 | 14,381 | 34,475 | 71,905 | 100,667 | 359,525 | 503,335 | 2,516,675 |
| -1 | -5 | -7 | -25 | -35 | -73 | -175 | -197 | -365 | -511 | -985 | -1,379 | -1,825 | -2,555 | -4,925 | -6,895 | -12,775 | -14,381 | -34,475 | -71,905 | -100,667 | -359,525 | -503,335 | -2,516,675 |
